About GutBrain

Science-backed news on the gut microbiome — translated into clear, honest, actionable content.

GutBrain is an independent science news site covering the latest research on the gut microbiome — the 38 trillion microorganisms living in your digestive tract that influence nearly every system in your body: your brain, your skin, your immune system, your metabolism, and your mood.

We launched in 2026 because most health content on the internet either ignores the science entirely or overstates it. Gut microbiome research is one of the fastest-moving fields in medicine — and it deserves better coverage.

Our Editorial Approach

Every article on GutBrain is grounded in peer-reviewed research. We link to primary sources, explain the methodology behind key studies, and are explicit about the strength of the evidence — whether it's a large randomised controlled trial or a small preliminary finding.

We believe in nuance. The microbiome field moves fast, and early-stage findings rarely tell the whole story. We'll tell you when the evidence is strong, when it's preliminary, and when something is mostly marketing.

We don't sell supplements, take affiliate commissions on products we review, or accept sponsored content. Our only agenda is accuracy.

Who We Write For

GutBrain is written for curious, health-conscious readers who want more than a listicle. You don't need a science background — we explain the terminology and put findings in context — but we won't talk down to you either.

Whether you're dealing with a specific gut issue, trying to optimise your diet, or just fascinated by the emerging science of the microbiome, you're in the right place.
